Question

X class mathematics text book has 392 pages. it is broken up in to two parts, paper 1 and paper 2. paper 1 is 12 pages less than paper 2. write suitable pair of linear equation in two variables
​

Answer 1

Answer:

Step-by-step explanation:

Let paper 1 = x

Let paper 2=y

y-x=12

Answer 2

Answer:

The suitable pair of linear equation in two variables is : y - x = 12

Step-by-step explanation:

Total number of pages in the mathematics textbook of class X = 392

Number of parts in which the mathematics textbook of class X is divided = 2

So, number of variables in our required linear equation = 2

Now, given that the paper 1 has 12 pages less than that of paper 2

So, Number of pages in paper 2 is greater than that of number of pages in paper 1

Let number of pages in paper 1 = x and number of pages in paper 2 be y

⇒ x < y

Also, paper 1 is 12 pages less than paper 2

⇒ y - x = 12

Thus, The suitable pair of linear equation in two variables is : y - x = 12
